Why don't these fund numbers match?

Two ledgers can each be internally correct and still produce different numbers for the same LP — that's what reconciliation is, not evidence that someone made an error. The work behind every capital account statement is proving that two systems which were never required to agree still describe the same reality.

Where the GL and the LP allocation actually split

The GL tracks cash and commitments at the fund level: capital calls in, distributions out, fees and expenses booked against the whole vehicle. The LP-level allocation takes those same events and splits them across LPs by ownership percentage and fee arrangement. The two are expected to reconcile to the same economic outcome. In practice, the place they most reliably diverge is timing — the GL books an accrual the moment an expense is incurred, while the LP allocation often isn't updated until the cash actually moves. Between those two points, the GL and the LP schedule are both right, and they don't match, because one is describing an obligation and the other is describing a payment.

Why the LP finds it first

LPs increasingly maintain their own shadow records and reconcile a fund's capital account statement against them, and ILPA's DDQ 2.0 formalizes this as a standing due-diligence question. The reconciliation often happens because an LP asks for it, not because the reporting workflow required it first — which means an accrual-timing gap surfaces on the LP's side of the table before the fund's own operations team has run its own check.

The two systems were never guaranteed to agree

A capital account statement that doesn't tie out isn't proof of carelessness — the fund GL and the LP allocation are two correct systems, built on the same underlying transactions, that were never structurally required to converge. Reconciliation isn't the process of correcting bad numbers. It's the process of proving two correct systems still describe the same reality.
